Structural Engineering of Buildings

To support a sustainable society, there is a high demand for developing comprehensive techniques to meet safety and performance requirements of buildings adequately while keeping the cost and material use minimum.

For this purpose, our research aims (1) to better understand the process of building collapse and its fundamental characteristics and (2) to develop design procedures to attain structural performance requirements in a more sound and reasonable way.

Special efforts are being made to establish new and innovative structural design methods, based on mechanics, computational engineering, and structural optimization, for building structures, long-span spatial structures, membrane structures, tensegrity structures, deployable structures, and structural parts such as passive control devices.

 

For evaluation and improvement of structural performance subjected to severe environmental conditions, such as earthquakes and high winds, we are conducting the following researches:
1. Vibration-based and vision-based structural performance evaluation
2. Analysis and control of wind-induced vibration of slender structures
3. Stability and form-finding of tension structures
